Title: Circuit breaker
Inventor: KANEO SHIGERU
IPC: H01H33/08
Filed: 1991-05-09
Abstract: PURPOSE:To prevent circuit breaking performance from being deteriorated because of the wear of contacts as well as to enable high amperage current at the time of short circuiting to be made low by providing both an arc runner and a slit plate which force an arc to be transferred to a stationary contact shoe. CONSTITUTION:When high amperage current such as short circuiting current and the like flows, an arc is generated with a movable contact 3 separated from a stationary contact 4. Arc resistance is increased because the cross sectional area can not be increased in the plate holding direction with the generated arc held by a slit plate 9. Moreover, arc energy is absorbed by the plate 9 with the arc brought into contact with the plate 9 while the arc is lowered in temperature, so that arc resistance is also increased. Furthermore, pressure built up by the arc is turned out to be force pushing up a movable contact 1, and arc resistance is thereby increased with the rotation of the contact increased in speed. In addition, when the arc is transferred to a runner 8 by means of the runner 8 just after both the contacts 3 and 4 have been separated, its transfer is accelerated by the use of the plate 9, both current limiting performance and circuit breaking performance can thereby be enhanced.

Title: Light transmission plate
Inventor: FUJINAGA NORIO
IPC: G02B6/00
Filed: 1995-04-27
Abstract: PURPOSE: To extremely efficiently extinguish shadows of mutual grooves by light rays reflected on the grooves and to obtain unmottled uniform brightness on the upper surface of a light transmission plate by forming recessed grooves crossing each other on respective synthetic resin surfaces opposed to each other. CONSTITUTION: The recessed grooves crossing each other are separately formed on the surfaces 2 and 3 opposite to a synthetic resin plate 1. As for the surface 3, it is preferable to form an inclined plane, or a circular-arcuate surface orthogonal to light rays as it goes away from a light source, and also, it is possible to use several synthetic resin plates 1 while overlaying one on top of another. Besides, it is preferable to form the groove 4 so as to be made deeper as it goes away from the light source, and the groove can be formed extremely small in depth. Thus, the shadows of the mutual grooves are extremely efficiently extinguished by the light rays reflected on the grooves 4 and 5 crossing each other formed on the surfaces 2 and 3 opposed to each other, then, the unmottled uniform brightness is obtained on the upper surface.

Abstract: PURPOSE:To improve the detection accuracy of the distance between a head and an optical disk by detecting the distance between the head and optical disk roughly by the 1st detecting mechanism and then detecting it accurately by the 2nd detecting mechanism. CONSTITUTION:The 1st detecting mechanism detects light emitted by a light emitting element 86a and reflected by a timing disk 85 by a photodetecting element 86b. Peaks of the detection level of the photodetecting element 86b in the rotation of the timing disk 85 are counted by a control part to detect the position of the head 48 roughly. The 2nd detecting mechanism, on the other hand, uses the focus mechanism composed of a projection lens 63 and a photodetector 64. The output waveform of the detection signal of the photodetector 64 has a constant pattern as the optical disk 5 rotates while rough position control is performed by the 1st detecting mechanism. The control part positions the head 58 accurately at invariably specific distance from the optical head 5 according to the relation between the pattern of the output waveform of the photodetector 64 and the distance between the optical disk 5 and head 48.

Title: Propulsion unit using paddle plate performing reciprocating movement
Inventor: SUZUKI SHIGEO
IPC: B63H1/36
Filed: 1995-03-24
Abstract: PURPOSE: To perform simple propulsion of a boat and a marine vehicle with a man power by a method wherein a hand row handle part is horizontally reciprocated and a paddle plate is oscillated in a given angle range through the medium of a resilient body to generate a propulsion force. CONSTITUTION: One side of a paddle plate 1 is fixed to a support member 2 clamping a resilient body 3 therebetween. When the handle part 5 of a horizontal member 4 is led to effect horizontal reciprocating movement, the support member 2 effects horizontal reciprocating movement in water around a fulcrum 6. Since contrary to the above, the tip part of the paddle plate 1 follows in a delay at a given angle with a radial direction, the support member 2 pushes water in an intermediate direction between a movement direction and the rear of a boat and the boat is pushed by means of a reaction force thereto. This constitution eliminates a need for a heavy and long Japanese scull and an oar and performs operation without needing a skill and training. By horizontally fixing the paddle plate 1, reciprocating movement with legs is also practicable.
